• Brand
  Shimano
• Series
  105
• Groupset
  105 R7100
• Tier

• Intended use
  Road
• Weight (claimed average)

• Shifting type
  Mechanical

  Gear shifting can be mechanical or electronic. Mechanical systems use cables to move derailleurs, while electronic ones rely on battery-powered motors. Wired electronic setups connect shifters and derailleurs with wires; semi-wireless systems use wireless links from shifter to junction box, then wires to the derailleur; fully wireless systems link shifter and derailleur directly.

• Front speeds
  2

  Number of chainrings on the crankset.

• Rear speeds
  12

  Number of cogs on the cassette.

• Max front diff
  16 teeth

  The max front diff is the largest tooth count gap between chainrings a rear derailleur can manage. A greater difference requires a longer rear derailleur cage to handle extra chain slack. On a single chainring system, the difference will be 0.

• Top gear teeth
  50-52 teeth

  The number of teeth on the largest chainring that the front derailleur can accommodate.

• Chainline
  44.5 mm

  Chainline refers to the distance between the centreline of the frame and the centreline of the chainrings.

• Chain stay angle
  61-66 deg.

  Front derailleurs are engineered to work within specific chain stay angle ranges. Consult the frame geometry chart to ensure that the front derailleur is an appropriate fit.

• Mount
  Clamp

  This is the method for attaching the front derailleur to the bike frame. Front Derailleurs come in versions for different mount types; confirm your frame’s compatibility.

• Clamp sizes
  286-with-s-adapter, 318 and 349 mm
• Cable routing
  Bottom pull

  Cable routing refers to the direction in which the gearing cable is drawn from the front derailleur to the frame. Make sure the cable routing on the frame matches the pull direction on the front derailleur.

• Cable adjuster
  Yes

  A small mechanism that allows for fine-tuning the tension of the derailleur cable
